The Specialized Tarmac Sl6 Disc Expert Ultegra Di2 Road Bike is no longer available, although you may find similar or newer versions below.

When we developed the Tarmac Disc we didnt just want it to be fast. We wanted it to be fast everywhere. Long climbs windy flats Grand Tour stages local fondos—we built a race bike to be the most complete out there. How’d we do it? We started with our Rider-First Engineered™ frame with a perfectly-tuned ride quality for every size added in some serious aero tech that makes it 45 seconds faster over 40 kilometers than the Tarmac SL5 and then made it 20% lighter. Nothing is lighter faster and better handling. The build spec on this Tarmac Disc is value-packed featuring Shimano Ultegra Di2 electronic shifting and hydraulic disc brakes a Roval C 38 Disc carbon fiber wheelset S-Works Turbo tires and our fan-favorite Power saddle.

• For the construction of the Tarmac we utilized advanced aerospace composite optimization software to revolutionize the construction and layup of our new FACT 10r carbon. Its the most schedule weve ever made and this allowed us to shed nearly 200 grams. Thats right a 20% reduction in frame weight—the perfect recipe for your next hill climb PR.

• 500 pieces creating 7 different sizes with the same tuned ride–that’s Rider-First Engineered™. We examine every ply of carbon on every frame size to ensure that all of our performance targets come through. To make sure you get the perfect ride every frame gets a unique layup schedule with different ply arrangements orientations quantities of material in specific areas and sometimes even exclusive thicknesses and types of carbon itself.

• Aerodynamics is the most important thing we can do to make you faster but with the Tarmac we added aero features without any cost to weight. Through development three areas were discovered where we could add aero for free—a new fork shape dropped seatstays with aero tubes and a D-shaped seatpost and seat tube. The result? A Tarmac that’s approximately 45 seconds faster over 40 kilometers.

• The updated the geometry is based on countless Retül data points and professional rider input. This enabled us to develop a Performance Road Geometry that perfects the combination of a responsive front-end and short wheelbase which delivers instantaneous response and optimal power transfer.

• For additional compliance the seatpost has flex built-into the upper 120mm where clamping doesnt happen. We also dropped the seatstays altered the seat tube shape and added tire clearance up to 30mm.
